“…[ 22 ] Therefore, it is essential to design an efficient sensor for Zn 2+ or establish testing methods with facile, inexpensive features. Traditional detection methods for Zn 2+ include inductively coupled plasma mass spectrometry [ 23 ] and atomic absorption spectrometry. [ 24 ] Nevertheless, some disadvantages of these methods are not negligible, such as expensive instruments, tedious preparation, and professional and time‐consuming operation.…”

The trace element Zn2+ plays an important role in the human body, but it is challenging to realize its qualitative and quantitative detection. Herein, inspired by the specific detection of the commercial dithizone to Zn2+, a series of polyacylhydrazones with polymerization‐induced emission (PIE) properties were successfully prepared and applied to the specific recognition and detection of Zn2+. It was found that all selected monomers did not emit fluorescence. In contrast, the as‐prepared polyacylhydrazone could emit strong fluorescence at 455 nm, due to the intramolecular aggregation of acylhydrazone groups along the macromolecular chains, indicating a significant PIE effect. As we expected, the polyacylhydrazone could specifically recognize and detect Zn2+ ions from 17 metal ions by the significantly enhanced fluorescence with a lower limit of detection (LOD) of 66 nM. Additionally, the complexation ratio of 2:1 between the repeating units in polyacylhydrazone and Zn2+, the coordination of Zn2+ with N and O atoms on acylhydrazone groups, and the fluorescence enhancement induced via intramolecular proton transfer were confirmed by 1H NMR and FT‐IR measurements. In conclusion, the successful preparation of PIE‐active polyacylhydrazones and the specific detection of Zn2+ ions provide a useful reference for the molecular design of new functional materials on the base of the traditional detection methods.This article is protected by copyright.
